How Big an Industrial Solar System Do I Need?
| System size | Annual generation (Melbourne) | Annual bill saving est. | Roof/ground space required | Incentive type | Best suited to |
|---|---|---|---|---|---|
| 100–150 kWLarge commercial | 133,000–200,000 kWh/yr | $33,000–$70,000/yr | ~600–900 m² | LGC ongoing revenue | Large warehouses, factories, distribution centres |
| 150–300 kWIndustrial | 200,000–400,000 kWh/yr | $50,000–$140,000/yr | 900–1,800 m² | LGC ongoing revenue | Manufacturing, cold storage, large logistics |
| 300 kW+Large industrial | 400,000+ kWh/yr | $140,000+/yr | 1,800+ m² | LGC ongoing revenue | Major manufacturing, multi-site portfolios, ground-mount |
Estimates based on Melbourne solar irradiance (~4.4 peak sun hours/day) and commercial grid tariffs of $0.25–$0.35/kWh. Actual results vary by site. All figures before LGC revenue.
Sized Right for Your Facility
Different industrial sites have different load profiles, roof structures and grid connection considerations.
Warehouses & Logistics
Large, unobstructed roof space is ideal for solar. Racking, forklifts and dock equipment create steady daytime load. Often the easiest industrial roof to design for.
- Large flat roof area
- Steady daytime load
- Ground-mount option
Manufacturing & Production
Machinery, compressors and production lines run through daylight hours, often on three-phase power — high self-consumption makes for fast payback.
- High daytime draw
- Three-phase common
- Fast self-consumption
Cold Storage & Refrigeration
Refrigeration runs continuously, giving these sites among the highest and most consistent electricity demand — and among the strongest ROI cases for industrial solar.
- 24/7 base load
- Highest usage profile
- Strong ROI case
Multi-Site Portfolios
Businesses with several industrial properties can stage rollouts across sites, standardising design and sharing engineering and procurement efficiencies.
- Staged rollout
- Standardised design
- Portfolio-wide reporting
LGCs, Staging Strategy & Financing
Industrial-scale solar has a different financial shape to small business solar. Here's what actually applies at 100kW and above.
| Mechanism | Applies to | Value | How received | Who applies |
|---|---|---|---|---|
| Large-scale Generation Certificates (LGCs) | Systems 100 kW and above | Approximately $20–$50 per certificate, earned per MWh generated. A 200kW system generating ~300 MWh/yr could earn $6,000–$15,000/yr | Ongoing annual revenue — sold through the Large-scale Renewable Energy Target (LRET) via a registered agent. | Registered LGC agent (Supply Solar advises) |
| Staged STC + LGC strategy | Sites near the 100kW threshold | Install 99kW first to capture the upfront STC discount, then expand later to access LGCs on the additional capacity | Two-stage project — Supply Solar models both stages against your roof capacity | Supply Solar designs the staging plan |
| Power Purchase Agreement (PPA) | Alternative to outright purchase, any size | Zero upfront cost — a third party owns and maintains the system, you buy the electricity at a fixed rate below grid price | Ongoing electricity payments at the agreed PPA rate, typically over 10-20 years | Supply Solar connects you with PPA providers |
| Instant Asset Write-Off / Depreciation | Portion of system under $20,000 (net of discounts) — for now | Full deduction in the year of purchase at your company tax rate on the eligible portion. Larger amounts depreciate over time. | Claimed in your business tax return. Consult your accountant for eligibility under current ATO rules. | Your accountant |
LGC values are approximate and subject to market rates. Tax incentive eligibility varies — consult your accountant. Supply Solar provides a full financial model in every industrial solar proposal.
What a 200kW Industrial System Delivers — Melbourne
A 200kW rooftop system is a common fit for a mid-sized warehouse or factory — above the STC threshold, earning ongoing LGC revenue on top of substantial bill savings. Here's what the economics typically look like.
Actual results vary by roof orientation, shading, tariff structure and self-consumption rate. Supply Solar models your specific site in every proposal.

Generate power at $0.05–0.10/kWh
Solar replaces grid electricity that costs Melbourne businesses $0.25–$0.40/kWh with energy at approximately $0.05–$0.10/kWh over the system's 25-year life — a locked-in, inflation-proof energy cost at scale.
2–4 year payback for daytime-load sites
Factories, warehouses and cold storage with consistent daytime and continuous loads self-consume most of what they generate — the fastest path to payback at industrial scale.
LGCs create ongoing revenue
Systems 100kW and above earn Large-scale Generation Certificates for every MWh generated — a revenue stream that continues year after year, on top of avoided grid costs.
PPA option removes capital barriers
Don't want to tie up capital? A Power Purchase Agreement gets your site generating with zero upfront cost — you simply pay for the electricity used, at a rate below grid price.
Pair with battery for peak demand savings
Add a commercial battery to cap peak demand charges — often 30–50% of an industrial electricity bill. Solar generates, the battery stores and discharges at peak to minimise demand-based charges.
ESG credentials and energy independence
Industrial solar demonstrates credible sustainability commitment — relevant to tenders, supply chain requirements and reporting obligations. And it removes exposure to future grid price increases.
How an Industrial Solar Project Works
Feasibility study
We review your electricity bills, roof or ground structure, and electrical infrastructure, and model LGC revenue against your projected generation.
Engineering & proposal
You receive a detailed proposal: system size, expected generation, LGC revenue projection, payback period, and a purchase vs PPA comparison.
Grid connection & approvals
We manage the DNSP network impact study, grid protection equipment specification, council permits and all compliance documentation.
Installation & commissioning
Our CEC-accredited team installs on schedule, commissions the system and monitoring, and registers the site for LGC creation.
Accredited, Award-Winning & Fully In-House
CEC-accredited — required for LGC eligibility
LGC eligibility requires a CEC-accredited installer and compliant engineering. Every Supply Solar industrial installation is completed by our own accredited team — protecting your revenue, warranties and grid approval.
2023 CEC Award & 2024 EUPD Award
Independent industry recognition of installation quality and customer experience — the benchmarks that matter to a business making a large capital investment.
LGC set-up handled end-to-end
Registration with a registered LGC agent, ongoing certificate creation and sale management — we don't just install the system, we set up the revenue stream that comes with it.
O&M contracts — protect your investment
Annual industrial solar maintenance — monitoring, thermal scanning, cleaning, inverter checks — keeps your system generating at its rated output, and your LGC revenue accurate, for the full 25-year life.

What Melbourne Industrial Sites Say
"200kW on our Dandenong warehouse. They modelled the LGC revenue against our actual bills, managed the whole DNSP approval, and had us generating in 6 weeks. Electricity bill dropped over 50%."
"Wanted to understand the STC vs LGC decision properly before committing. Supply Solar modelled both a 99kW staged approach and going straight to 150kW — the numbers made the choice obvious for our site."
"Cold storage runs 24/7 so our load profile made solar an easy decision once we saw the numbers. Grid connection took longer than a small system would but Supply Solar managed the whole DNSP process for us."
